Remote System Tie-ins:ILN Intergration

From ReservesDirect: Open Source EReserves System

RD connects to the ILN 3 times. All three actions occur within the zQuery.class.php file. This only applies to physical items. This class is currently TIGHTLY tied to Sirsi Unicorn. If you are a Sirsi customer please contact the mailing list for assistance using the Sirsi API.

Barcode Request

• Method:. zQuery::zQuery
• search_term (string). value to be searched
• search_field (string). field to search. ['barcode' || 'control'] default = control
• If search_field is 'barcode' the $g_zhost:4321 is queried to return the 'control' number associated with this barcode
• Otherwise the search_term is returned unaltered

zQuery Data Retrieval

• Method:. zQuery::zDoQuery
• query (string). "@attr 1=12" + <search_term from zQuery::zQuery>
• start (string). "0"
• limit (int). "1"
• Issues a z39.50 request to $g_zReflector?host=$g_zhost&port=$g_zport&db=$g_zdb resulting xml if valid is parsed and used to prefill the physical items screen

       copy     = copy number (int)
       callnum  = item call number (string)
       loc      = item owning location  (string)
